Demonstrates basic methods for isolating one element from other elements. Experiments include: the reaction of sodium peroxide and water, catalytic decomposition of hydrogen peroxide, catalytic decomposition of potassium chlorate, decomposition of mercuric oxide, distillation of liquid air (an example of physical rather than chemical preparation), condensation from air, and electrolysis of water. Includes various ways to collect and test for oxygen. From the Yale Chemistry series... Topics: 16mm Film, Educational Film, Oxygen, Chemistry, Catalysis, History, Laboratory techniques, Chemical...

Created during WWII for the U.S. Navy, "Fly High and Live" is a training film that explains to pilots the use of the oxygen cylinder, diluter-demand regulator and type A-14 mask. The type A-14 was based on designs by Dr. Arthur H. Bulbulian of the Mayo Clinic Aero Medical Unit (his patent was applied for on July 1, 1943 and approved on June 6, 1944). Dr. Bulbulian and his colleagues, Dr. Walter M. Boothby and Dr. W. Randolph Lovelace II, had previously designed a nasal oxygen mask...

On the 13th of April, after docking with the Lunar Module, the astronauts, Jim Lovell, Fred Haise, and Jack Swiggert, discovered that their oxygen tanks had ruptured and ended up entering and returning to Earth in the Lunar Module instead of the Command Module. There is footage of inside module and Mission... Topics: NASA, APOLLO 13 FLIGHT, COMMAND MODULES, GROUND SUPPORT SYSTEMS, HISTORIES, LUNAR EXPLORATION,...
